ToclZ whom it may concern:

Be it known that I, FRANCIS HENRY Qu r- TALL, a subject of the King ofGreat Brltain, residing at Manor Works, Braintree, in the county ofEssex, England, have invented certain new and useful Improvements inBlanks for Making Metallic Window Sashes and Frames, of wh' ch thefollowing is a specification, a

The object of my invention is to provide a blank from which thevariousparts of the marginalmetallic frame of a swinging window sash, and themarginal frame of the window may be constructed without the addition ofother parts. Suchsashes and window frames are commonly built up ofseveral pieces secured together to provide the requisite stop flangesand Weathering strips and to permit a proper hinge connection betweenthe sashes and window frames.

According to my inventlon, I provide a blank having such formation thatby cutting Fig. 1.

away certainparts and without the addition of other parts it may beshaped to form any one of the four marginal pieces of either the sash orthe window frame.

In the accompanying drawings, Figure l is a perspective view of aswinging sash with a window frame made in accordance with my invention.Fig. 2 shows a transverse section through my improved blank. Fig. 3shows a transverse section through the marginal bottom piece of the sashand the bottom piece of the window frame when the window is closed, thesection being taken at the right-hand side of the hinge shown in Fig. 4shows a horizontal section through the side pieces of the frames on thei left-hand side of Fig. 1 when the window is closed. Fig, 5 is asimilar view at the righthand side of Fig. 1. Fig. 6 is a perspectiveview of the blank which may be employed for all parts of the frames, butindicating by dotted lines how the blank is cut to form the bottom pieceof the window frame. Fig. 7

pearance ofthe blank after it is cut in the manner indicated in Fig. 10.Fig. 12 is a perspective view of the blank showing by dotted lines howit is cut to form the top piece of the sash. Fig. 13 shows theappearance-ofthe blank after the proper parts. are removed. Fig. 14 is aperspective view of the blank; and Fig. 15 shows the appeai ance of theblank after a part has been re-. moved to form the left-hand side pieceof the marginal frame of the window frame. Fig. 16 1s a perspective viewof the blank indicating by dotted lines where it is cut to form theleft-hand side piece of the sash.

Fig.1? is a perspective view of the blank after it is cut to form theleft-hand side piece of the sash. Fig. 18 is a perspective view of theblank indicating by dotted lines where it is cut to form, the rlght-handside of the window frame; and Fig. 19 shows the shape of the blank afterit is cut. Fig. 20 is a perspective view of the blank showing by dottedlines how it is out to form the righthand side piece of the sash frame;andFig. 21 shows the appearance of the .blank after it is cut in themanner indicated in Fig. 20.

In Fig. 1, A indicates the marginal frame of the swinging sash which ishinged at w to the window frame B. The sash frame comprises the bottompiece A, top piece A and side pieces A A which are welded or otherwisesuitably secured together at the, corners. The window frame 13 comprisesthe bottom piece B, top piece B and side pieces B B The two frames areso formed as to provide double weathering, i. 0., there are overlappingflanges on all parts of the frames so arranged as to ekclude wind andweather, the flanges being cut away at suitable parts to provide for thehinge connection, as shown in Fig. 1-, and to allow the sash to swingproperly. The four parts of the window frame B have outwardly projectingflanges b forming a continuous channel allaround the outside of theframe and short inwardly projecting flanges 12 forming acontinuous-channel all around the inside of the frame. The four piecesof the sash frame have short outwardly projecting flanges a forming acontinuous channel around the outside of the sash frame and theseflanges register with the flanges b when the sash is closed. The bottompiece formed wah a front flange b a flange at b The left-hand sidepiece, BF.

is formed with a front flange b (but nocorresponding back flange) andthe righthand side piece B has a back flange b, but' no correspondingfront flange. The bottom piece Ais formed with a front flangev a.

' and a back flangeat a", each of these flanges 1 extending only partwayfrom end'to end of the sash. The top piece A has a rear flange a andafront-flange at a. The lefthand side iece A has a rear flange a? withno correspon ing frontflange, and the righthand side piece has a frontflange a with no corr onding back flange; By this construction the sashframe. and the window frame may behin ed together in such man .ner thatthe sas when .the sash is closed there will be double can freely swingand weathering, z'. e.,' there will be front and rear flanges which willfit tightly. together and exclude wind and rain without packing orgifidapplication of additional strips of any By employing a blank of thekind shown in cross section in Fig. 2, any oneof the diflerent parts ofthe two frames may be made without the addition of other parts. Thus, inFig. 6 if the blank S be cut on the dotted lines it will produce theformation shown in Fig. 7 which is suitable for the bottom piece oftli'ewindow frame. If the blank be cut on the dotted lines shown in Fig.8 a suitable foi-mation will be produced for the top piece of the windowframe. When the lank is cut in the manner indicated in Fig. 10, asuitable formation for the bottom piece of the sash is produced and whenthe blank .is out in the manner mdicated'in Fig. 12,

the top piece of the sash is formed. I By cutting the blank in themanner indicated by dotted in...liig. 14' a suitable shapefisproducedfor the left-hand side iece of the window frame and theleft-han sidepiece'j n of the. sash frame ma 7 be made asindicatedin Figs. 16 and 17.T e rightihandside piece of the'window frame maybe obtained'as'indicated in Figs. 18 and 19 and therighthand side piece of the sashframe ma beobtained in the manner indicated i 20 and 21. As the mannerof cutting e blanks 1s clearly indicatedin the drawing no furtherdescription appears to be necessary.

By reference to Fig. 2 it wi11 be observed that the blank comprisesa-body' portion 8 having parallel flanges 3' projectin from one side,short flanges 8 in hne wlth the flanges s but projecting from .theopposite sides'of the body portion 8 and flanges .8 which connect withthe outer sides of the flanges s 'projecting beyond the outer ends ofsaid flanges s and being out of line with the flanges s and 8 I claim asmy invention:

A metal blank for metallic sashes and window frames having alongitudinal body portion formed on one side'near its op osite edgeswith outwardly projecting anges forming a channel between them and onits
